This application claims the benefit of priority from U.S. applicationSer. No. 14/370,335, filed Jul. 2, 2014, which is a 371 ofPCT/EP2012/076311, filed Dec. 20, 2012, which claims benefit of U.S.Application No. 61/603,982 filed Feb. 28, 2012, and of prior FrenchApplication No. 1250017, filed Jan. 2, 2012 the entire contents of whichis hereby incorporated by reference.

The present invention is directed towards proposing liquid cosmeticcompositions comprising alkylcellulose, which are intended in particularfor making up and/or caring for the lips or the skin, especially thelips, which are capable of producing a deposit, especially a makeupdeposit, which shows good cosmetic properties, especially in terms ofcomfort, absence of tack and gloss.

In general, cosmetic compositions need to afford an aesthetic effectwhen applied to the skin and/or the lips, and to maintain this aestheticeffect over time.

Specifically, the production of an aesthetic effect, after applying acosmetic composition, results from an assembly of properties intrinsicto the composition which are expressed in terms of makeup performance,cosmetic properties such as comfort on application (ease of application,glidance on application) and while wearing the composition (freshnessand/or no sensation of pulling), satisfactory homogeneity, lightness andgloss of the deposit produced with the composition.

In particular, the production of a liquid composition which ishomogeneous and stable over time at 24° C. and at 45° C., and whosedeposit on the skin or the lips is uniform, fresh and light andsufficiently glossy without developing tack, is an ongoing preoccupationof formulators working in the field of lipsticks and other skincareand/or lipcare products.

Ethylcellulose is already known in cosmetic and/or therapeuticcompositions, as a film-forming agent, for facilitating the formation ofa film on the skin and/or the lips, and for improving the waterresistance of this film.

Unfortunately, ethylcellulose, and alkylcelluloses in general (with analkyl group comprising from 1 to 6 carbon atoms), is of limitedsolubility in the majority of the solvents commonly used in cosmeticand/or dermatological formulations. In general, monoalcohols containingfrom 2 to 8 carbon atoms, such as ethanol, butanol, methanol orisopropanol, are preferred for dissolving sufficient amounts ofethylcellulose in cosmetic or pharmaceutical compositions. Evaporationof the C₂-C₈ monoalcohols leads, after application of the correspondingcosmetic composition to the skin or the lips, firstly to concentrationof the deposit and secondly to the formation of a coat on the surface ofthe skin or the lips that has a very good wear property. For example,document WO 96/36310 proposes cosmetic compositions especiallycomprising ethylcellulose dissolved in ethyl alcohol (SDA 38B-190 or SDA40B-190 solvents).

However, these volatile monoalcohols have the drawback of beingpotentially irritant to the skin and/or the lips, and consequently mayprove to be detrimental in the case of repeated use on the skin.

In order to overcome this problem, it has been proposed in document U.S.Pat. No. 5,908,631 to use, as an alternative to C₂-C₈ monoalcohols, acertain number of solvents for ethylcellulose, such as lanolin oil,certain triglycerides, certain propylene glycol or neopentyl glycolesters, isostearyl lactate, and mixtures thereof.

Unfortunately, replacing these C₂-C₈ monoalcohols, which are volatilecompounds, with these non-volatile solvents may on the other hand proveto be detrimental in terms of comfort and of a fresh sensation andlightness of the resulting deposit.

Consequently, there is still a need for cosmetic compositions, which arefree of C₂-C₈ monoalcohols, comprising a sufficient amount ofalkylcellulose, and which are capable of forming on the skin and/or thelips a deposit that has gloss and comfort properties and that issparingly tacky or non-tacky.

There is more particularly a need for compositions for making up and/orcaring for the skin and/or the lips, which are homogeneous and stableover time (especially for 72 hours at 24° C. and for 72 hours at 45°C.), in particular which do not undergo phase separation, which are easyto apply and which allow the production of a uniform, light, fresh,non-migrating deposit which, in particular, is sparingly tacky ornon-tacky and satisfactorily glossy.

One aim of the invention is to propose a composition whose texture ishomogeneous and stable at 24° C. and at 45° C.

The object of the present invention is, precisely, to satisfy theseneeds.

As emerges from the examples presented below, the inventors havediscovered that the abovementioned expectations can be satisfied byformulating the alkylcellulose in the form of a dispersion in water witha mixture of specific oils other than C₂-C₈ monoalcohols.

Thus, according to a first of its aspects, a subject of the presentinvention is a liquid cosmetic composition comprising, in aphysiologically acceptable medium:

-   -   at least 20% of water, preferably at least 30% of water;    -   at least alkylcellulose, the alkyl residue of which comprises        between 1 and 6 carbon atoms, preferably between 2 and 6 carbon        atoms and preferably between 2 and 3 carbon atoms, preferably        ethylcellulose;    -   at least one first oil, the said first oil being a        hydrocarbon-based non-volatile oil, chosen from:        -   C₁₀-C₂₆ alcohols, preferably monoalcohols;        -   optionally hydroxylated monoesters, diesters or triesters of            a C₂-C₈ monocarboxylic or polycarboxylic acid and of a C₂-C₈            alcohol;        -   esters of a C₂-C₈ polyol and of one or more C₂-C₈ carboxylic            acids,    -   at least one second oil, the said second oil being a        non-volatile oil chosen from silicone oils and/or fluoro oils;    -   at least one third oil, the said third oil being chosen from        hydrocarbon-based oils other than the said first oil;    -   at least one, preferably nonionic surfactant.

Advantageously, a cosmetic composition according to the invention ishomogeneous, stable (no exudation or phase separation) over time(especially after 72 hours or even 1 month at 24° C. and at 45° C.),easy to apply to the skin and/or the lips, and produces a uniform, fine,light and fresh deposit that is non-migrating and without a sensation ofdryness or pulling, non-tacky or sparingly tacky, and satisfactorilyglossy.

The composition according to the invention is in liquid form at 20° C.

The term “liquid” is intended to mean a composition capable of flowingunder its own weight, at 20° C. and at atmospheric pressure (760 mmHg),as opposed to compositions said to be as “solid”.

Preferably, the cosmetic compositionaccording to the invention is a liquid lipstick, such as a gloss forexample or a “stain” for the lips.

The term “stain” is intended to mean a very fluid composition whoseviscosity is less than that of a conventional gloss. A lip stain may beapplied with a lip brush for example, and makes it possible to obtain afiner deposit than that obtained with a conventional gloss compositionfor the lips. In general, the thickness of a film obtained with acomposition of “stain” type is preferably between 5 μm and 30 μm,preferably between 5 and 20 μm.

The composition according to the invention also concerns a process formaking up and/or caring for the skin and/or the lips, preferably thelips.

Protocol for Measuring the Viscosity:

According to this embodiment, when the composition according to theinvention is in the form of a paste at 20° C. (the term “paste” or“butter” means a composition that is therefore not solid, and whoseviscosity can be measured), its viscosity may be measured according tothe following protocol:

The viscosity measurement is carried out at 20° C., using a RheomatRM180 viscometer equipped with a No. 2 spindle for the very fluidformula (whose viscosity is less than 0.7 Pa·s) or with a No. 3 spindlefor the slightly thicker formulae whose viscosity is greater than 0.7Pa·s, and in particular between 0.7 and 1.5 Pa·s, the measurement beingcarried out after rotating the spindle for 10 minutes (at the end ofwhich time stabilization of the viscosity and of the rotational speed ofthe spindle are observed), at a shear rate of 200 s−1.

The composition according to the invention has at 20° C. a viscosity ofbetween 0.05 and 1.5 Pa·s and preferably between 0.08 and 1 Pa·s.

Particularly preferably, the viscosity at 20° C. of a compositionaccording to the invention is between 0.1 and 0.7 Pa·s.

A composition according to the invention comprises at leastalkylcellulose, the alkyl residue of which comprises between 1 and 6carbon atoms, preferably between 2 and 6 carbon atoms and preferablybetween 2 and 3 carbon atoms, preferably ethylcellulose.

According to one particularly preferred embodiment, the alkylcellulose(preferentially of C₂ to C₆, preferentially ethylcellulose) is presentin a composition according to the invention in a content (solids)ranging from 1% to 60% by weight.

Particularly preferably, the composition according to the inventioncomprises from 2% to 30% by weight of alkylcellulose (preferentially ofC2 to C6), and more preferably still from 2.5% to 20% by weight,relative to the total weight of the said composition.

The alkylcellulose is a cellulose alkyl ether comprising a chain formedfrom β-anhydroglucose units linked together via acetal bonds. Eachanhydroglucose unit contains three replaceable hydroxyl groups, all orsome of these hydroxyl groups being able to react according to thefollowing reaction:RONa+C₂H₅Cl→ROC₂H₅+NaCl,in which R represents a cellulose radical.

Advantageously, the alkylcellulose is chosen from methylcellulose,ethylcellulose and propylcellulose.

According to one particularly preferred embodiment, the alkylcelluloseis ethylcellulose.

It is a cellulose ethyl ether.

Total substitution of the three hydroxyl groups would lead for eachanhydroglucose unit to a degree of substitution of 3, in other words toa content of alkoxy groups of 54.88%.

The ethylcellulose polymers used in a cosmetic composition according tothe invention are preferentially polymers with a degree of substitutionwith ethoxy groups ranging from 2.5 to 2.6 per anhydroglucose unit, inother words comprising a content of ethoxy groups ranging from 44% to50%.

According to a preferred mode, the alkylcellulose (preferablyethylcellulose) is used in a composition of the invention in the form ofparticles dispersed in an aqueous phase, like a dispersion of latex orpseudolatex type. The techniques for preparing these latex dispersionsare well known to those skilled in the art.

The product sold by the company FMC Biopolymer under the name AquacoatECD-30, which consists of a dispersion of ethylcellulose at a rate ofabout 26.2% by weight in water and stabilized with sodium lauryl sulfateand cetyl alcohol, is most particularly suitable for use as an aqueousdispersion of ethylcellulose.

Thisliquid fraction at 23° C. preferably represents between 15% and 85% andmore preferably between 40% and 85% by weight.

Within the meaning of the invention, the melting point corresponds tothe temperature of the most endothermic peak observed in thermalanalysis (DSC) as described in Standard ISO 11357-3; 1999. The meltingpoint of a pasty substance or of a wax may be measured using adifferential scanning calorimeter (DSC), for example the calorimetersold under the name MDSC 2920 by the company TA Instruments.

The measuring protocol is as follows:

A sample of 5 mg of paste or wax (depending on the case) placed in acrucible is subjected to a first temperature rise passing from −20° C.to 100° C., at the heating rate of 10° C./minute, then is cooled from100° C. to −20° C. at a cooling rate of 10° C./minute and finallysubjected to a second temperature rise passing from −20° C. to 100° C.at a heating rate of 5° C./minute. During the second temperature rise,the variation in the difference in power absorbed by the empty crucibleand the crucible containing the sample of pasty substance or wax ismeasured as a function of the temperature. The melting point of thecompound is the value of the temperature corresponding to the tip of thepeak of the curve representing the variation in the difference in powerabsorbed as a function of the temperature.

The liquid fraction by weight of the pasty compound at 23° C. is equalto the ratio of the enthalpy of fusion consumed at 23° C. to theenthalpy of fusion of the pasty compound.

The enthalpy of fusion of the pasty compound is the enthalpy consumed bythe compound in order to change from the solid state to the liquidstate. The pasty compound is said to be in the solid state when all ofits mass is in crystalline solid form. The pasty compound is said to bein the liquid state when all of its mass is in liquid form.

The heat of fusion of the pasty compound is equal to the area under thecurve of the thermogram obtained using a differential scanningcalorimeter (DSC), such as the calorimeter sold under the name MDSC 2920by the company TA Instrument, with a temperature rise of 5° C. or 10° C.per minute, according to standard ISO 11357-3:1999. The enthalpy offusion of the pasty compound is the amount of energy necessary to makethe compound change from the solid state to the liquid state. It isexpressed in J/g.

The heat of fusion consumed at 23° C. is the amount of energy absorbedby the sample to change from the solid state to the state that it has at23° C., composed of a liquid fraction and a solid fraction.

The liquid fraction of the pasty compound measured at 32° C. preferablyrepresents from 30% to 100% by weight of the compound, preferably from50% to 100%, more preferably from 60% to 100% by weight of the compound.When the liquid fraction of the pasty compound measured at 32° C. isequal to 100%, the temperature of the end of the melting range of thepasty compound is less than or equal to 32° C.

The liquid fraction of the pasty compound measured at 32° C. is equal tothe ratio of the enthalpy of fusion consumed at 32° C. to the enthalpyof fusion of the pasty compound. The enthalpy of fusion consumed at 32°C. is calculated in the same way as the enthalpy of fusion consumed at23° C.

Preparation Protocol:

-   -   1) The fatty phase composed of the phenyl silicone oil, the        Parleam oil and pigments previously ground in 3/7 of        octyldodecanol was heated to 55° C. in a heating pan.    -   2) The surfactant was added and the mixture was stirred at        55° C. until homogeneous.    -   3) The ethylcellulose and the octyldodecanol were poured into a        beaker. The mixture was then stirred using a Rayneri-type        deflocculator for 1 hour at 55° C., followed by addition of the        water, the gelling agent and the preserving agent, and the        mixture was stirred with the Rayneri deflocculator at 55° C.        until a homogeneous mixture was obtained.    -   4) In a second heating pan, this mixture was then poured into        the fatty phase and stirred (Rayneri deflocculator) until the        mixture reached room temperature. The ethanol was then added and        the mixture was stirred for 5 minutes.    -   5) The product was finally packaged in lip gloss pots.

After 24 hours at room temperature, the compositions obtained wereevaluated and their viscosity was measured according to the protocoldescribed previously.

The stability of the compositions was evaluated by placing thecompositions obtained for 72 hours at 24° C. and for 72 hours at 45° C.The compositions were especially checked to see if phase separation, theformation of grains or a variation in viscosity was observed.
